Oral cancer is one of the more dangerous malignancies people face. But there are ways you can reduce your risk of this deadly disease through changes in lifestyle habits and behaviors.
Two of the better known behaviors for increased oral cancer risk are immoderate consumption of alcohol and the use of tobacco, particularly chewing tobacco and snuff. Eliminating these, especially the latter, can vastly improve your odds of avoiding cancer. Another factor is a strain of the human papilloma virus (HPV 16) that's transmitted sexually, which you can avoid through safe sex practices.
In addition to these lifestyle changes, there's one more you should make to lower your oral cancer risk: adjustments to your diet. Research over the last half century has provided ample evidence of a link between the foods we eat and our risk of all types of cancers, including oral.
The biggest concern is over certain elements in some foods that can damage DNA, the molecular “operating instructions” that regulate the formation and function of our bodies' cells. These elements are collectively known as carcinogens because of their role in cancer formation.
An example of a carcinogen is a group of chemicals called nitrosamines. These form during preservation processes using nitrites in meats like bacon or ham. They're also found in beer or certain preserved fish. To limit your consumption of nitrosamines, you should reduce these and other processed products and replace them with fresh fruits and vegetables, or organic meats and dairy products.
Our DNA can also be damaged by unstable molecules called free radicals that arise during normal cellular function. But there are also substances known as antioxidants that help protect the cells from free radical damage. Many plant-based foods contain nutrients like vitamins C and E that have antioxidant properties, so including them in your diet could help reduce your oral cancer risk.
Several clinical studies over the years have been consistent in their findings that a diet rich in fresh fruits and vegetables can reduce the risk of oral or throat cancers, as well as other forms of cancer. Making changes to your diet in that direction, plus other lifestyle changes, could help you avoid this devastating oral disease.

Eating is one of the pleasures — and necessities — of life, but people who suffer from temporomandibular joint disorders (TMD) may find eating no pleasure at all — and they may not be eating the right nutritional balance of foods.
TMD is a collection of conditions that affect the jaw joints, connecting muscles and other related facial structures. If you've been diagnosed with TMD, you're probably not only acquainted with severe pain, but also difficulty opening your jaw as widely as normal. This can make it difficult to chew certain foods.
There are a number of effective treatments for TMD, including thermal therapy (hot or cold packs), joint exercise, medication or surgery (as a last resort). But these treatments often take time to make a noticeable difference. In the meantime, you may still need to change what and how you eat to ensure you're getting the nutrients your body needs.
The overall strategy should be to soften and reduce the chewing size of your food. With fruits and vegetables, you'll want to peel and discard any hard or chewy skins, and then chop the fruit flesh into smaller pieces. Steam or cook vegetables like greens, broccoli or cauliflower until they're soft and then chop them into smaller portions. You might also consider pureeing your fruit (and some vegetables) to make smoothies with ice, milk or yogurt, or vegetable-based soups.
Treat meat, poultry or seafood in much the same way, especially biting sizes. Besides cooking meats to tenderness, include moisteners like broths, gravies or brazing liquids to further make them easier to chew.
Dairy foods are an important source of nutrition: eat milk-based products like yogurt or cheese as much as you can handle. If you have problems with these or also nut butters, then consider meal replacement beverages like instant breakfast or whey protein beverages.
And don't forget whole grains. Although some can be hard to chew, you can prepare them in hot cereal form (like oatmeal) to tenderize them. You can also prepare thin bread toast and cut into smaller pieces.
Hopefully, your treatment will bring your TMD symptoms under manageable control. Until then (and after, if need be) adjust your diet to eat the foods that keep you healthy.
Good nutrition is vital for maintaining health and preventing disease, especially for your mouth. A diet rich in whole foods — fresh fruits and vegetables, protein and dairy products — and low in sugar will not only promote strong teeth and gums, but lessen your chances of developing tooth decay or periodontal (gum) disease.
Diet is also a prominent factor in reducing the risk for another serious mouth disease — oral cancer. While oral cancer makes up only 3% of total cancer cases reported annually, the five-year survival rate is a sobering 50%, much lower than for other types of common cancers. While genetics plays a role in your susceptibility to oral cancer, lifestyle choices and practices present the greater risk factors for the disease.
Of these lifestyle factors, refraining from tobacco products, moderating your alcohol consumption and avoiding risky sexual behavior are of primary importance in reducing your cancer risk. With that said, you should also take into account the foods that are part of your daily diet — both what you should and shouldn’t eat. As an example of the latter, some foods contain a class of chemicals known as nitrosamines that are carcinogenic (cancer-causing). One such chemical, nitrite, is used as a preservative in meats like bacon or ham, and may also be found in beer, and seafood products.
On the positive side, your diet should be rich in foods that supply antioxidants, substances that protect the body’s cells from damaging, unstable molecules known as free radicals. The best sources for antioxidants (more so than dietary supplements) are plant foods rich in fiber and vitamins C and E. Eating more of these may also reduce your intake of nitrates, animal fat and saturated fat.
Adopting a moderate, nutritious diet, along with exercise, can have a huge positive impact on your general health and quality of life. Along with other lifestyle changes, better dietary choices can also help ensure a healthy mouth and reduce your risk of oral cancer.
